Well Sandy, if you did get another cat and yours shows up at the door, how would you feel about having three cats?
If we get cats again, it will definitely be two. They really need each other as companions since we humans can't spend every waking moment playing with them - as much as we might like to! :lol:
If you're OK with having three cats, then my two cents is to get another one. In the mean time, I hope your little girl does come home.
